Nanobodies, or single-domain antibodies, are smaller and simpler than conventional antibodies, but they have huge potential. Since this potential is being explored by multiple research teams, any one team has difficulty producing standout work. Yet researchers from two Göttingen institutions, the Max Planck Institute (MPI) for Biophysical Chemistry and the University Medical Center, assert that they have developed nanobodies that are truly special.
These nanobodies can block the SARS-CoV-2 virus, but that’s not especially distinctive. Nanobodies developed by other researchers can do that, too. What sets the nanobodies from Göttingen apart, the Göttingen researchers pointed out, is that they can bind and neutralize the virus up to 1,000 times better than previously developed nanobodies. The Göttingen nanobodies can also, in the researc ....

Mini-antibodies efficiently block SARS-CoV-2 virus


Mini-antibodies efficiently block SARS-CoV-2 virus
Göttingen researchers have developed mini-antibodies that efficiently block the coronavirus SARS-CoV-2 and its dangerous new variants. These so-called nanobodies bind and neutralize the virus up to 1000 times better than previously developed mini-antibodies. In addition, the scientists optimized their mini-antibodies for stability and resistance to extreme heat. This unique combination makes them promising agents to treat COVID-19. Since nanobodies can be produced at low costs in large quantities, they could meet the global demand for COVID-19 therapeutics. The new nanobodies are currently in preparation for clinical trials.
Antibodies help our immune system to fend off pathogens. For example, the molecules attach to viruses and neutralize them so that they can no longer infect cells. Antibodies can also be produced industrially and administered to acutely ill patients. They then act like drugs, relieving symptoms and sho ....

Single-Domain Antibodies a.k.a. 'Nanobodies' from Alpacas Help Fight Against SARS-CoV-2 Infections and Its Mutations


28 July 2021, 09:07 pm
Single-Domain Antibodies, also known as Nanobodies, have been discovered from Alpacas, and are now used against the SARS-CoV-2 virus. The notorious SARS-CoV-2 is also known as the virus which causes COVID-19, and the said nanobody treatment helps in preventing it from infecting the body s cells, as well as its mutations.
Blocking COVID-19 from cells is better protection than having no shield from it. Nanobodies from camels have initially been reported to be protecting against COVID-19 and prevent it from spreading and causing a chain reaction within the body.

Experts have reason to believe those who tested positive to COVID-19 again are non-infectious. ....
